PostPosted: Wed May 11, 2016 9:01 am    Post subject: [SOLVED] Gentoo on Intel 550 freeze after loading kernel Reply with quote

Hi everybody,

I am trying to install gentoo on a laptop with an intel IRIS 550 onboard graphics with gnome/cinnamon + systemd and luks (+ lvm) encryption + UEFI.
My problem is that the system freezes immediately after the grub output "loading initramfs" "loading kernel".
No caps, no num lock; not even a CTRL-ALT-DEL works.
I am coming from arch linux () and have some experience in UEFI, LUKS + LVM encryption and installing a system from the command line,
but I am at my wit's end since I don't even get an error message/log.

I think the main problem is related to the onboard graphics (which is the only installed graphics card; there is no dedicated one).
My IRIS 550 (or its graphic acceleration) is only supported by the recent rc Linux Kernel (4.6) so I am using the gentoo sys-kernel/git-sources.
I installed gentoo following the handbook (for amd64) and chroot, emerge, ... are working.
I am of course using an initramfs using genkernel and the i965 Video driver is exported correctly in the /etc/portage/make.conf.
I hard compiled the intel graphics driver into the kernel as recommended in the intel wiki entry.

I have the notebook not with me right now (since I can't use it) so I'll post the files (kernel .config, grub.cfg, /etc/default/grub , USE-Flags, ...) and commands (genkernel, ...) I used later.

My first question is:
Is there an option to check if a kernel is actually loaded by grub and hangs after that or to check if my grub grub.cfg is just wrong?
I used an gentoo live dvd on an usb stick and already found something about that this may be a source to my issue:
https://forums.gentoo.org/viewtopic-p-7240690.html

Thanks in advance!

Do you have any drivers built-in that require firmware? If so, you need to have that firmware built-in too, or change the drivers to build as modules. Else the kernel will stall around 60 seconds waiting for each missing firmware file.
If you suspect that the Intel graphics causes problems: To check whether that is the case, enable CONFIG_FB_SIMPLE and CONFIG_X86_SYSFB in the kernel config, and in your bootloader pass the video=inteldrmfb:off kernel parameter. (CONFIG_FB_EFI should not be necessary but probably won't hurt either.)

I havent't checked any firmware modules yet, but I recompiled the kernel using your options and changed the grub_cmdline.
No success; same error as before.
I'll let the laptop stay in this "loading initramfs" for a while (30 minutes or so) so I can check if a module is missing; but I can't really imagine that this is the solution, because my system really freezes; no CAPS LOCK, no CTRL-ALT-DEL; nothing except the power button works....
normal and fallback initramfs fail to boot as descripted above.
My genkernel command:
Code:
genkernel --udev --lvm --luks initramfs

Here are the files:

and the kernel .config:
EDIT May 14, 2016.
deleted because the kernel .config was too long.
You'll find the file below as pastebin link.

Seems that you hit the maximum post length, your kernel configuration is incomplete.

No, either use a pastebin or post only the interesting parts:
CONFIG_DRM_*
CONFIG_FB_*
CONFIG_FRAMEBUFFER_CONSOLE

Use wgetpaste. It is a package that you should be able to install in your chroot if you still have it up. Otherwise you can simply paste the .config in a pastebin site and post the url here.

wgetpaste works by using wgetpaste <file> or <command> | wgetgpaste The command will return a url.

Code:
# CONFIG_X86_SYSFB is not set
CONFIG_X86_SYSFB=y
Huh? Did you edit the configuration manually? Don't do that (it says so right in the beginning), this messes things up.

I just assumed # is a comment.
I just edited these both entries manually but I can of course change/delete them.
(or completely )
Btw. I think the half an hour is over; my laptop is still frozen.
So whatever the problem is:
it doesn't change just by waiting

run "make oldconfig" to reset the configuration into a consistent state. Set CONFIG_DRM_I915=m via menuconfig (you can press / to search in menuconfig).

I used the livecd/dvd kernel .config and changed the i915 to a module and the kernel is now loading, but failing to locate the system partition (this is related to my luks).
(Yeah, I know this may be definitely not recommended).
And I'll have to admit:
Your (gentoo's) documentation really sucks hard.
I am sorry to have to say that, but:
The documentation recommends to change grub.cfg directly which is - in my opinion - actually worse than editing the kernel's .config manually.
And a wiki page for using good old "mkinitcpio" does not even exist; but ok.
I'm now trying to fix my kernel boot parameters.
How do I tell genkernel to load kernel modules or load kernel modules in gentoo?

Why are just all documentation writers uuid-nazis?
Well this would not even be a problem if they just would SPECIFY WHICH UUID they want the user to use.
partuuid or uuid?
Using the "uuid" output of blkid gives the following issue:
Device [uuid of luks partition] doesn't exist or access denied.
Could not find the "root_[uuid of luks partition]-main-arch" in [uuid of luks partition]

even using partition id is failing.
The error has the same structure:
Device [partuuid of luks partition] doesn't exist or access denied.
Could not find the "root_[partuuid of luks partition]-main-arch" in [partuuid of luks partition]

I've just switched back to arch linux and it (booting, loading kernel and even using an accelerated X) is working now.
My steps:
compile and install the 4.6 (as I write this kernel has still rc status) linux kernel (using linux-git from aur)
compile and install the recent libdrm (at least 2.4.68) (using libdrm-git from aur
boot the kernel using grub2 and mkinitcpio
login and execute startx.
System runs without any problem.

So thanks for your help and the gentoo concept of building the whole system directly from sources may be (actually is) amazing,
but right now I don't have the time and need a working linux.
But I'll definitely install gentoo on my (now) old laptop, if/when I have time.
